OIL SUCTION AND COLLECTING APPARATUS FOR STEAM-ENGINES.

Patented Nov. 12, 1907.

Application filed November 6, 1906- Serial No. 342.185.

To all whom it may concern:

Be it known that I, OESARE ORENGO, chief marine engineer, a subject of the King of ltaly, residing at 38 Via Casaregis, in the city of Genoa, Province of Genoa, Kingdom of Italy, have invented a new and useful Improvement in Oil Suction and Collecting Apparatus for Steam-Engines; and I do hereby declare the following to be a full, clear, and exact description of the same.

This invention relates to an improved oil suction and collecting apparatus for steam-engines, its object being to prevent the lubricating-oil of the piston rods and' slide-rod, from entering, inside the cylinder, and thence ii'ito condenser and boilers. The apparatus therefore is chiefly useful in connection with marine steam-engines.

In the accompanying drawing: Figure 1 shows a front view in partial section of the apparatus. Fig. 2 shows the connection in partial section of the apparatus ith the piston-rod stalling box,

The apparatus consists in a metallic box adivided in two portions or chambers bc each independent l'rom the other, ind hermetically closed. A pipe -(Z is connecting said chambers, which by means of a three-way-cock e, may be put, at will, in communication one with the other, and both with a receiver The top part of said receiver is connected with bottom of chamber b also by means of pipe provided with cock lz-. The receiver fis also provided with a cock -2' at the top, and cock l at the bottom: the latter is connected with a discharge pipe. The object of cock is to establish, at will, the atmospheric pressure inside of the receiver. For the same purpose chamber ZJ- has on the top a cock m establishing at will the atmospheric pressure inside of said chamber. The upper part of chambers Z c is provided respectively with valve nand cock -o-. Valve n of chamber -b is connected through a pipe to the condenser of the steam-engine. Cock -o oi'chamber -c is connected by a pipe, and through the openings pq, with the annular space 7' in the pistonrod stuffing box. Said space is left open between the annular rings s placed immediately above the towpacking.

The way of working of the apparatus is the following: Into chambers band -care poured about two inches of water, through the doors placed in front of said chambers. Valve n and cock 0- are then open, and chambers -Z) and c are put in communication through cock 0, and the oil mixed with the water from space 7 is sucked into box a. When wishing to discharge the water collected in chamber -b, without stopping the Working of the apparatus, the receiver -f, is put in communication with chambers -b and cby means of three-Waycock -c, while this latter still keeps in communication chamber b With chamber c. After few minutes the vacuum is formed in the receiver f-: cock -e is turned again in its first position, and cock his opened so that water from chamber bdis charges itself into receiver After the water in chamber -b has reached its normal level, cock'h is shut, and by opening cocks and l, the Water collected in the receiver f may be discharged, to waste. When wishing to take out the oil collected in b and c-, the working of the apparatus must be suspended: cock mis then opened for establishing the atmospheric pressure inside of box a so as to allow the easy opening of the doors of chambers bc through which doors, the oil collected is taken out. The suction action of the apparatus is controlled by opening more or less the valve 'n oi chamber b*.

Having now described myinvention I declare that what I claim is:

1. In an oil suction and collecting apparatus for steam engines a box comprising two chambers which communicate at their bases one with the other and provided with a cock, a communication from a stuffing box of the engine to one of said chambers, a condenser and a communication from the other of said chambers to said condenser.

2. in an oil suction and collecting apparatus for steam engines, a box comprising two chambers, a pipe whereby said chambers communicate one with the other, a receiver for water from said chambers, a pipe connecting said receiver with the lirst-inentioned pipe, and a three\vay cock at the junction of said pipes.

3. In an oil suction and collecting apparatus for steam engines, a box comprising two chambers a pipe whereby said chambers communicate one with the other, a receiver for water from said chambers, a pipe connecting said receiver with the iirst-n1cntioned pipe, a three-way cock at the junction of said pipes, and a condenser connected with said receiver and independently of the pipes aforesaid.

-i. In an oil suction and collecting apparatus for steam engines, a stufling box, a condenser, a box comprising two chambers one communicating; with said stufling box and the other communicating" with the condenser, a pipe whereby said chambers communicate one with the other, a receiver for water from said receiver with the firstmentioned pipe, a pipe independent of those named for connecting the receiver with the chamber connected as aforesaid with the condenser, cocks which put the receiver and last-mentioned chamber in communication with the atmosphere, and a discharge cock for the receiver.
